Funky behavior with scales and rotation when changing actor hierarchy. about flaxengine HOT 6 CLOSED

@mafiesto4 is there a reason this is on 1.9? I think this is a pretty big bug considering it's basic transformation operations, those should probably be stable for a release version lol

Ah okay. This will account for more delay on the update tho.

This might be a regression from 9a21cfd.

I don't know how to fix this. Clearly Actor::SetParent should calculate _localTransform differently when worldPositionsStays=true but Transform is limited to a single Translation+Rotation+Scale so when changing transformation hierarchies this might not be possible to preserve transformation properly. We would need to migrate to matrix-only usage representing any linear transformation. I tested this and Unity seems to not handle it properly as well so it's not an obvious issue.

Oh yeah, you are right lol
Weird. I guess I will have to find some other way to organize my meshes then? Or just not use scale

I've asked in the Unity discord about this issue, and apparently it is expected behavior or at least a known problem that needs to be worked around. Maybe this can be closed.
